Any ideas?

For some reason, I've been having the darnedest of times with silver paint pens. These two pucks, signed by New York's Marian Gaborik, are the latest example of my futile efforts.

Beyond priming them before each use (shaking them, as suggested, as well as making sure the paint is flowing) I've tried switching brands, using new and old, and even keeping them capped after priming. Nothing, however, seems to lead to a decent autograph.

It's particularly frustrating, too, that these came from a player of Gaborik's quality and star power. Because the Rangers head back to Hockey Bay in April, I'm seriously considering wiping them clean and trying again. This time, though, I'll use a blue paint pen.
